Manholes

Packaged Metering Manholes (PMMs) are a watertight and corrosion resistant way of measuring below-grade flows. Each PMM integrates a fiberglass manhole tube, flow device, cover, base, and access ladder. PMMs can be combined with other manhole units for a variety of complete solutions.

Flume Metering Manholes integrate flumes to measure open-channel, below-grade flows in a single watertight and corrosion resistant solution. Each Flume Metering Manhole integrates a fiberglass manhole tube, flume, cover, base, and access ladder.

Commonly used for wastewater applications, where full-pipe conditions are present, Mag Meter Manholes are a watertight and corrosion resistant. Each Mag Meter Manhole integrates a fiberglass manhole tube, cover, base, access ladder, and includes installation of a mag meter you supply. 

When you’re looking for an economical option to slow the flow through a pipe system, consider Energy Absorbing Manholes (EAMs). Each watertight and corrosion resistant unit includes a fiberglass manhole tube, energy-absorbing structure, mounting flange, cover, and base.

Diversion Manholes allow you to control, direct, and distribute underground flows in pipes (that don’t run full). Starting with our watertight and corrosion-resistant fiberglass manhole tube, each unit can be configured with interior drops, Y-channels, or J-bends to best meet your needs.

Use Storm Water Manholes to remove trash, floating debris, and contaminants from collection systems. Static or removable screening structures can be integrated into a fiberglass manhole tube for a watertight solution that’s also corrosion resistant.

Keep sewage flow moving smoothly by integrating an in-line grinder. Grinder Manholes start with a watertight fiberglass manhole tube that’s corrosion resistant and add a channel to mount your grinder and rail system. Both open-channel and full-pipe grinders can be integrated.

Fiberglass manholes can be customized with a variety of accessories to meet the specific needs of your job. Find solutions for air circulation, depth adjustments, equipment or mounting panels, storage, work surfaces, and more.
